Origins of Fajitas

Fajitas have a rich history that dates back to the early 1930s. The term “fajita” itself is derived from the Spanish word “faja,” which means belt or sash.

Traditionally, fajitas were made using less desirable cuts of beef such as skirt steak, which were marinated and tenderized to impart flavor. Cowboys and ranch workers along the Texas-Mexico border would cook these tough cuts over an open fire and wrap them in flour tortillas for a hearty meal.

The origins of fajitas can be traced back to Mexican vaqueros (cowboys) who migrated from northern Mexico to south Texas during the late 19th century. These cowboys brought with them various cooking techniques and flavors that heavily influenced Tex-Mex cuisine.

However, it wasn’t until the 1980s that fajitas gained widespread popularity across the United States. A meat company called Vidal Ranches began marketing skirt steak as “fajitas” to appeal to American consumers’ growing interest in Mexican food. This clever marketing strategy led to an explosion in demand for fajitas, making them one of America’s favorite Tex-Mex dishes.

Today, fajitas come in various forms, including chicken, shrimp, and vegetable options alongside traditional beef versions. They are typically served with grilled onions and peppers, guacamole, sour cream, salsa, and other condiments.

Fajitas have become a staple item on menus at Tex-Mex restaurants worldwide due to their versatility and delicious flavors. Whether enjoyed at home or ordered out at a restaurant, these sizzling hot platters of flavorful meats wrapped in warm tortillas continue to captivate taste buds everywhere.

So next time you bite into a juicy fajita filled with tender meat and vibrant toppings, remember its humble origins as a cowboy’s meal along the Texas-Mexico border.

Making The Best Grilled Chicken Fajitas

This meal is great for a quick weeknight dinner or maybe a Cinco de Mayo celebration, or that summer BBQ. The kids absolutely love this meal, whether they are making full blown fajitas or just picking away at the grilled seasoned chicken.

Grilled Chicken Fajitas Marinade

Start off by seasoning the chicken, we are going to want to marinade these chicken breasts for about 4-5 hours. Longer is ok but 4-5 hours is about the minimum you want. Here is what you are going to need for the marinade:

  • olive oil
  • lime juice
  • water
  • salt
  • cumin
  • minced garlic
  • paprika
  • black pepper
  • chili powder

Combine these ingredients into a bowl, and whisk together well. Add the chicken breasts into a resealable bag and then pour the marinade into the bag over the breasts. Place the bag into the refrigerator and let marinade, as I mentioned about 4-5 hours.

When they are done marinating, remove the breast and pat dry. We then want to season with a dry rub that consists of some paprika, cumin and cayenne pepper. Mix them together and lightly coat the top and bottom of the chicken breast. Save a little for the peppers and onions later on in the process. While you are working on the final steps of preparing the chicken you can get the grill up and running. We are looking for 350° on the grill and can set the grill up for direct heat grilling.

Easy Grilled Chicken Fajitas

The grill should be up and running at an ambient temperature of 350°. As I mentioned above, the chicken breast we are going to grill over direct heat. I usually suggest wiping the grate down with some vegetable oil to avoid the chicken from sticking to the grate.

Place the breasts on and close the grill. You are going to do these about 8 minutes on each side. Chicken is usually done at 165°. My suggestion is to pull it at 160°, and we are going to give it a 15 minute rest period, during which you will get to that 165° temperature. When resting, cover with some foil.

I used my ThermoPro TP19H to spot check the chicken breasts during the cooking process.

Cooking Peppers and Onions

When it comes to the peppers and onions, they will take a little longer than the chicken, so I would suggest starting a little before you start the chicken. I used the following combination of peppers but you can go with what you like. My only suggestion is to not go with just green peppers or red peppers but try to mix it up with at least some green and red or some other combo.

I used 2 green, 1 red and 1 orange pepper for this chicken fajita recipe. Cut them into strips, remove the seeds and we are going cook in a cast iron skillet on the stove top. You will want one white onion cut in half and then sliced. You can cook the peppers and onions on the grill as well if you have room. Warm your skillet up and then add some olive oil or water, if you are looking for something a touch healthier.

You can then sauté the peppers until you see them start to soften a bit. At this point add the onions, the onions will cook faster than the peppers so you do not want to put them in at the same time. Take a little of the seasoning and add it to the peppers and onions.

You can choose to pull the peppers and onions once they soften up, I like leaving them in the skillet while they crisp and get a little bit of char on them. Once they are done to your liking, pull them off and let them cool down a bit for serving.

Making The Fajitas

With the chicken finished on the grill and it rested, you can start slicing it. I slice it the length of the breast and then depending on the thickness of the breast, again in half. I used fajita sized flour tortillas and started off by layering on the sliced grilled chicken, then peppers and onions and then started to garnish it. I like my fajitas simple and top them off with a dollop or two of sour cream. The seasoning combinations we used will keep you from feeling like you need a lot of additional flavor.

Some other suggestions to top off the fajitas are: avocado, cilantro, salsa, grated cheese or sautéed jalapenos.
